The TAVR procedure allows physicians to replace a diseased aortic valve without open-heart surgery. This procedure enables the placement of a heart valve into the body with a catheter, which allows the valve to be inserted through a small incision into an artery.he TAVR procedure generally is performed in much less time than open-heart surgery. Additionally, open-heart surgery can require a two-to three-month recovery period, compared to the recovery period of only a few days with the transcatheter approach.
